These are a must if you have aftermarket filters and/or exhaust. Search forums for a good starting place and maybe get a few different sizes to dial in the best performance. I dropped these into my '79 XS1100 and it made the most of the pod filters and exhaust I installed. You will have to re-synch your carbs after installation. I searched everywhere for these and Bike Bandit has the cheapest and already in a 4 pack.

Q:

Are these a direct fit replacement for the main jets on a 1999-2002 carbuerated Yamaha R6?

Thank you for your question. The round main jets are replacement for Super BN carbs. That is most commonly used on personal watercraft. Please let us know if there is anything else we can do for you by contacting us by email at Sales@bikebandit.com, Live Chat or by phone toll free at 888-339-3888. We are more than happy to help.

Q:

I have a 1992 Suzuki GSX-R750 (not Cali model). My stock main jets are 127.5. I have a Vance & Hines slip on and I'm running lean so I need a bigger jet. I think these are what I need, but I don't know if I need the large round or small. Will either work?

Thanks for your question! We would not be able to confirm if these would fit for you unless they are stated for the machine on the website in a kit. We would only be offering the OEM jets from Kawasaki which are the stock size that come in the bike.
